  • Essential Laboratory Apparatus: Definitions and Uses
    Here are 10 laboratory apparatus and their uses:

    1. Beaker: A cylindrical container with a spout, used for holding, mixing, and heating liquids. They are often graduated, but not precise enough for accurate volume measurements.

    2. Erlenmeyer Flask: A conical flask with a narrow neck, used for holding and mixing liquids, especially during titrations or reactions where swirling is required. They can also be used for heating.

    3. Graduated Cylinder: A tall, cylindrical container with markings indicating volume. Used for measuring precise volumes of liquids.

    4. Burette: A long, graduated tube with a stopcock at the bottom. Used for dispensing precise volumes of liquids, especially during titrations.

    5. Pipette: A narrow, graduated tube with a bulb at the top. Used for transferring small, precise volumes of liquids.

    6. Funnel: A cone-shaped utensil with a stem, used for transferring liquids or powders from one container to another, or for filtering solids from liquids.

    7. Bunsen Burner: A gas burner with a controlled flame, used for heating substances.

    8. Test Tube: A small, cylindrical glass tube used for holding, mixing, and heating small amounts of liquids or solids.

    9. Stirring Rod: A glass rod used for stirring solutions and suspensions.

    10. Tongs: A tool with two arms for gripping and holding hot or dangerous objects, like test tubes, beakers, and crucibles.
